On the main questioner 76 are by means of a Tregarir.es Q8 • Fig. i; two rearwardly directed arms 100 (FIG. 6), which come into engagement with a stop, are fastened in an inverted U-shape, the outer ends of which are connected to one another by a tubular bar 102. At the lower end of the coupling part 28 of the elevator 24 a base part 1C4 is attached, the lower end is provided with a downward extension 106. An adjustable stop I08 is screwed into the extension 106. The table 26 after engagement of the rollers QO with the Kut ζΘ is further moved upward, causing the weight of the row crop approach is that the same is pivoted downward; 'counterclockwise, as shown in Figures 2 and _t 1 j? demonstrate'.; to the tube 102 with the stopper IO8 <engages around the pivot movement of the corn harvest approach by stopping down. Thus, when the rollers QO engage the grooves 58, the corn head 72 is pivotally supported on the table, but its downward or counterclockwise pivoting movement is limited by the engagement of the arms 100 and tube 102 with the stop 108 a downward projection 109 is provided, which forms a cavity with the stop 108 and the extension 106, which receives the tube 102 »

Trunnion 110 is rotatable between two limit positions, namely by an eccentrically arranged spring 114 which is fixed between the hook 112 and the table 26. If the hook 112 is rotated counterclockwise about the pin 110 according to FIG. 5 until the spring 114 has settled transversely to the axis of the pin 110, the hook 112 can be twisted into a disengaged position, which is also interrupted in FIG lines shown _t Conversely, the hook 112 from the disengaged position to the engaged position to be moved, which is shown in Fig. 5 in solid lines ,, by the locking hook is rotated 112 about the pin 110 in a clockwise direction until the spring 114 again the axis of the pin 110 goes away to load the hook 112 in a clockwise direction. A too far-reaching movement of the Hekens 112 is prevented by a pin 116 which em connector JO 1st attached and which projects into the path of the leading edge of the hook 112th In the engaged position of the hook 112, the tube 102 is picked up by the same and prevented from separating from the table, so that the row harvest attachment is rigidly connected to the table 26.

The manner in which the combine harvester is converted into a corn harvester is shown in the successive phases in FIGS. 1, 2 and 3. In Fig. 1, the jig reel J4 is carried by the arms 36 and driven off the output shaft 44 by the belt 40. The knife rail pQ is driven by the belt 42, which runs around a pulley II8 (FIG. 8) which is arranged on the trowel 44. The shaft 44 is rotatably mounted in a support arm 120 which is attached to the rear viand 26b of the table 26. The reel J4, the support arms 36, the belt 40 and the associated pulleys 41, 4 ^ and 45 (FIG. 1) are removed from the table 26. The pistons of units 96 are retracted about table 26 and elevator 24 about the axis of shaft 25

until the table coupling elements or guides 56 are aligned with the coupling elements or rollers QO of the shark harvest set in the axial direction and are arranged below the same. Because the Kühdrescher 'is in the axial direction against the maize harvest. 72 moves (to the left, as shown in FIGS. 1, 2 and 3) until the rollers 90 engage in the coupling grooves 58. The locking hairs 112 are then rotated from the disengaged position to the engaged position (FIG. 5) and the pistons of the units 96 are moved out to move the table and {

to raise the elevator according to FIGS. 1 and 2 about the axis of the shaft 25 clockwise.

Once the table 26 has moved upwards, the weight of the corn harvest set 72 causes it to pivot counterclockwise about the rollers 90 so that the arms 100 and the tube 102 swing upwards until the tube 102 against the front edge 112a (Fig. 5) of the locking hairs 112 and rotates the same counterclockwise about the pin 110. The tube 102 is therefore received in the carbon space between the extension 109 and the extension I06 and rests against the stop 108 (Fig. 7). The counterclockwise movement of the pawl 112 caused by the movement of the tube 102 into the cavity is insufficient to cause the spring 114 to move across the axis of the pin 110. Pie spring 13Λ has the effect that the locking hook 112 returns to its engaged position and engages the tube X02, as FIG. 5 shows. Before the coupling of the tube 102 to the hook 112, the pin II6 prevents the hook 112 from moving too far by engaging the front edge of the inside of the hook 112. When the locking hook 112 is engaged with the pipe 102, the corn harvest kit 72 is rigidly connected to the table because the hook 112 is a

According to FIG. 8, an input coupling element 124 is at 12.5 on the V.'elle 44 healed = the coupling element 124 is provided with a raised, non-circular part 128, which has a complementary shaped outlet in the axial direction coupling element 126 receives. The coupling element 126 is provided with two grooves 132 with a ball lock 134 cooperate, which assigns ε-nge in the coupling element 124 is, In the position shown in Fig. 8, the output coupling element 126 is shifted to the left and is with a flat I30 in engagement, which on the Pulley II8 is designed to be the same with the V.'elle 44 to couple.

A sprocket I36 is rotatably mounted on a cylindrical part of the coupling element 124. A chain wheel 140 is arranged on the shaft 70 (FIG. 4) and can be connected to the chain wheel 136 by a chain 138. After the tube 102 has come into engagement with the locking hook 112. the coupling part 126 is shifted to the right in order to come into engagement with a flat 142 on the hub of the sprocket I36. So that the sprocket 136 is coupled to the vielle 44, the coupling part 84 (Fig =, 4) is shifted to the right In order to couple the shaft 70 to the shaft 86, the chain wheel 140 is fastened at V \ ^> to a friction clutch unit 144 by welding or in some other way non-rotatably, which includes a friction drum 146. The drum 146 is freely rotatable on the end of the shaft 70 and is provided with a friction lining 148 on the inside *

In order to decouple the row harvest from the table 26, the driver shifts the coupling part 84 to the left in order to decouple the shaft 70 from the shaft 86, and moves the locking hook 112 into the disengaged position, as shown in broken lines in FIG The hydraulic unit 96 is then withdrawn to lower the table 26 and elevator 24 about the axis of the trowel 25 until the corn crop attachment 72 rests on the soil, as FIGS. 1 and 2 show. A further downward movement of the table 26 causes the attachment to rotate relative to the table 26 about the rollers QO in the clockwise direction, the arms 100 swinging downward until they rest on the floor, as shown in FIG. 2. The continued downward movement of the table 26 separates the grooves 58 and the guide 56 from the rollers QO and the combine harvester can then be moved backwards by the row harvesting set 72 »

The row harvest attachment 72 can be operated with little or no physical effort on the part of the operator Table 26 can be coupled or uncoupled from the same.
